The device forming the subject matter of this application is adapted tobe employed for boring fishing holes in the ice. ln View of the factthat a fishing hole in the ice must be smooth, in order not to fray theiishing.

line, more is involved than simply making a hole of any kind in the ice,and the tool must be considered, not merely with respect to the holethat is bored, but, as well, `with respect to the fishing line, when theline is in use in the hole. Moreover, tools of the kind mentionedgenerally are operated by hand and not by power, because no power isavailable on the ice, and, therefore, the present tool is so constructedthat it will bore a hole with a minimum expenditure of power.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains. Y

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings:

Figure l shows in side elevation, ah tool constructed in accordance withthe invention;

Figure 2 is an end elevation;

Figure 3 is a transverse section taken approximately on the line 3 3 ofFigure l;

- Figure 4 is a longitudinal section;

Figure 5 is a fraginental side elevation. The device forming the subjectmatter of this applica-tion preferably is made of metal throughout. Itcomprises a tubular body, including a cylinder l. About the lower end ofthe cylinder l, a reenforcing collar 2 is secured. Because the collar 2is used,the cylinder l may be made lighter than would be the caseotherwise, and the entire device, therefore, may be rotated without theeX- penditure of great power, a consideration which is of importa-nce inconnection with a tool, which, ordinarily, is turned by hand.

The collar 2 is providedat its lower end` with I I i depending pointedteeth 3,. which slant out-l wardly at progressively increasingfangles.The collar 2 has short spiralribs 50 andll,

which are oppositely disposed.v 55

The collar 2 is provided at its lower end with -acircumerentia-lly-extended, upward ly-op'ening, outwardly-extended,trough- 'shaped reamer 4, which is locatedimmediately in advance of thetooth which has thernost pronounced outward slant, an observation whichwill be understood readily when Figure 2 of the Vdrawingsis noted. Thereamer is located at the lower end of the spiral rib 51, as Figure 5will show. The tool is further `characterized by the fact that thebottom 5 of the reamer4is disposed higher than the lower ends of theteeth 3, as shown in Figure l. Notingfthe point at which'the refer. encenumeral 36 is applied invFigure 2, it will be seen that the reamer 4extends laterallyan'd outwardly beyond the .circle in whichv operatesthe tooth which has the most pronounced outward slant. p :j

The cylinder lV is provided with spira ribs 7 and the `rib 50 onthering2 forming a 'continuation ofthe rib 7 Von the cylinder,` and the rib'51 on the ring forming a continuation of the rib 57 on the cylinder.4As shown at 6 in Figure 2, the reamer4 eX- tends outwardly to the outeredge of the rib 51e-57. The general construction shown at 3-4-36-6 issuch that a smooth hole will be'bored in the ice, the vertical outerwall of. the reamer 4 finishing `the hole, beyond .the tooth 8 which hasthe most pronounced outward slant, a clear space being made underneaththe ribs 7-50 and 57-51, the rib 57- 5l taking the loosened ice from thereamer 4,;V and carrying it upwardly,l when thebody of the tool isrotated, the reamer being at least f as wide as the area'cut by theteeth 3, and at least as wide as the ribs.

The tool may be rotated in any desired l may be4 secured a reeniorcingcollar v8, disposed within a cylindrical extension 9, of any desiredlength. Av headed securing element l0 passes removably through the upperend.,

of the cylinder 1, through the collar 8, and/'1130 through the lower endof the extension 9, and the securing element 10 may be held in place byits head, and by a cotter pin 11 mounted in the opposite end of thesecuring element. A bridge l2 is secured in the upper end of theextension 9, and carries a vertical shaft 14V which, being rotatedeither by hand, or by power, renders the` tool operative for thepurposes intended'.

Having thus described the invention, what is claimed is:

1. A tool for making fishing holes in the ice, comprising a tubular bodyprovided atits lower end with depending teeth which slant outwardly atprogressively increasing angles, thebody being supplied at its lower endwith a circumferentially-extended, upwardlyopening, outwardly-extended,trough-shaped end with reamer, located immediately in advance of thetooth which hasthe most pronounced outv ward slant.

2t. A tool for making lishing holes in the ice,

constructed as setr forth in claim l, and further characterized bythefact that the botr' tomY of the reamer is disposed higher than the lowerends of the teeth, thev rea-mer eX- tendinglaterallyand outwardly beyondthe circle in which said tooth moves.

3. A tool for making fishing holes in the ice, comprising a tubular bodyprovided at v,its lower end with depending teeth which slant outwardlyat progressively increasing anglesthe body beingl supplied at its lowera circumferentially-extended, upwardly-opening, outwardly-e X 't e n d ed, trough-Shaped reamer, the body being provided with a spiral riblocated above the teeth and leadingy from the reamer, the reamer beingat least as wide as the. area. cut by the. teeth',` and at least as wideas the rib.

In testimony that I claim the foregoing as `my own, I have heretoaffixed my signature.
